  • Patent number: 6421996
    Abstract: A harvester includes an integral two-section baling device with the section movement designed to provide both a bale discharge function and a transport height reduction function. In one embodiment, one section of the device includes rollers which follow a downwardly sloped ramp as the sections are opened relative to each other. The sloped ramped additionally serves as a portion of a finished bale handler and bale support. In a second embodiment, an additional hydraulic cylinder system controls the downward movement of the opened sections towards the transport position. Existing baler functions are advantageously utilized to provide transport height reduction with a minimal amount of additional hardware, and the operator can switch between transport and operational modes quickly and easily.

  • Patent number: 6263650
    Abstract: Cotton accumulator structure includes an upright storage area supported behind the cab of a cotton harvester. A screened upper cover area is supported above the storage area by hydraulic cylinders which move the cover between a raised harvest position and a lowered storage position for reduced transport height. As harvested material is directed through ducts towards the storage area, debris can exit through the screened cover. The lower end of the storage area includes an opening for egress of the cotton. Several shafts having timed projections are journalled for rotation adjacent the opening about parallel axes. The shafts, when not rotating, generally close the lower end and prevent cotton from falling through the opening. To meter the cotton from the storage area to an operating on-board processor, a drive is activated to rotate the shafts.
